We are constantly working on the software and we will release software when we feel that it is stable enough. A few issues were found as you can see in the bugtracker and we decided to fix the before we release the RC.

Our goal is to release stable software and we will not release a RC that has known issues. If you want to get a software on a given date, then you can just checkout the software at any date you want from our svn stable branch, the software is as stable then as if wo would have released it on that day.
